Congrats on your report for K-5 and good that it works out for you.

My pleasure! I will leave soon in a 7-day vacation and will probably spend even more time with the camera; if something relevant/additional will come up, I will most surely complement the original post.
Michael.
Thanks for the comparison Michael. Looking forward to seeing the results of your 7 day trip.

Fun how APS-C K5 would beat FF 7D. David met Goliath

But are you really determinant about seliing your C-7D -- despite some mechanical advantages of the 7D, like focus-point-selection-joystick?

7D is not FF

7D is APS-C. Exactly same target market as K-5

I can't justify two systems, especially since they would overlap too much (both crop, both on primes as I didn't come to like a Canon zoom too much). Let's say for now that Pentax system's small size won over Canon system's joystick ;-)

Nice writeup!

That lens release button on the K5 is freakishly loose, while the 7D is really built like a tank from all points of view.
Be careful. Some of us had ours fall off.

But.. anyway still the metaphor applies, see DxO.

Being a kind of David should ever be Pentax' trumpcard.

Well, the K5 kinda humbles the 7D......

K5 is just amazing after I read all about it... I think I'm going with RonHendriks1966 recommendation and upgrade to K5. I don;t even need f1.8 or less with that camera for low lighting.. Thank you guys..

Oh yeah, fast lenses are still Really Really Nice To Have. You get that extra margin for motion-speed and light-grabbing prowess. And you get finer DOF control. Slower or shorter lenses have thicker DOF -- great for many applications, not-so-great for others. Yeah, you can grab postcard images quite well with a K5 and any slow-ish zoom. But I rather like thin-DOF lenses, to surgically separate a subject from their surroundings. Call it art. Hmmm, I must create some postcards soon...

Note that even a fast 35 or 31 or 28 or 24 lens has thick DOF. For those who know 135/FF systems, 35/2 on a crop-sensor is roughly equivalent to 50/2.8. That's sharp but sorta pedestrian IMHO. DOF at 24mm and shorter can be immense at any aperture when not focused too close.

So, get the K5, and save up for some more lenses!

Thanks buddy. I'm thinking of adding 50-135 to my collection and perhaps sigma 50 prime for portrait.

I'll remind you Rico that most fast 50's on 24X36mm sensors only perform decently from f/2.8 and up - use apertures wider than this and the IQ starts to drop,especially in the corners. Also, why do you have to be so negative towards 50mm lenses? just think for a moment of where photography would be without them.

I think 50mm f.1.4 sigma is great for portrait too.

I only own 50 Fifty's. Can't never have enough...

But I like 50mm much better on a crop-sensor than full-frame. That long-normal FOV just doesn't excite me. I don't do much with 35-37mm on APS-C either, preferring 28mm. There's nothing *wrong* with 50/2.8 on 135/FF. It's just not a sexy combo. It's a bit (to me) like middle-C on a piano. Rumbling the bass notes, tinkling the treble keys -- exciting! Middle-C -- yeah, OK, that's nice...
